A sponge-type road pavement structure and its construction method

Abstract

This invention discloses a sponge-type road pavement structure and its construction method, belonging to the field of sponge-type road technology. It aims to solve the technical problem that in high summer temperatures, moisture evaporation in sponge-type road pavement leads to a harder pavement material and reduces its permeability. The invention includes a paving frame with several slots, a fixing nail fixedly connected to the bottom of the paving frame, a water-collecting tray at the bottom of the paving frame, a support fixedly connected to the inner wall of the paving frame, and a frame fixedly connected to the top of the support. By incorporating a drive fan blade, the water flow converts water energy into kinetic energy, causing the drive cylinder to rotate. During this process, rollers move on a wave-like annular curved surface, enabling the spray pipe to reciprocate. This allows for spraying of the permeable layer material at both near and far distances. Furthermore, by adjusting the pipe during spray pipe movement, damage to the pipe surface can be prevented, thus improving the protective effect on the permeable layer material.

Description

Technical Field

[0001] This invention relates to the field of sponge road technology, and more specifically, to a sponge road paving structure and its construction method. Background Technology

[0002] Sponge-type road pavement structure is an urban road design concept that mimics the function of a natural sponge. It aims to improve the city's ability to absorb, store, infiltrate, and purify rainwater, thereby reducing urban flooding, improving the urban water environment, and increasing urban green space. It can effectively manage rainwater runoff and achieve the natural accumulation, infiltration, and purification of rainwater.

[0003] Currently, during the high temperatures of summer, the moisture in sponge-type pavement evaporates rapidly, reducing its water retention capacity. In this process, the permeable pavement material becomes harder, reducing its permeability and thus affecting its performance in the rainy season. Therefore, we propose a sponge-type road pavement structure. Summary of the Invention

[0004] The purpose of this invention is to provide a sponge-type road pavement structure and its construction method to solve the technical problem that in the high temperature of summer, the evaporation of moisture in the sponge-type road pavement leads to the hardening of the pavement material and reduces the water permeability of the permeable pavement material.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a sponge-type road paving structure, comprising a paving frame with several slots, a fixing nail fixedly connected to the bottom of the paving frame, a water-collecting tray provided at the bottom of the paving frame with the fixing nail fixedly sleeved in the upper hole of the water-collecting tray, a support fixedly connected to the inner wall of the paving frame, a frame fixedly connected to the top of the support, a permeable layer fixedly connected inside the frame, a water storage tank provided at the bottom of the paving frame, and a protective mechanism provided between the water-collecting tray and the water storage tank; the protective mechanism includes a sleeve and a spraying unit; a water storage unit is provided inside the water storage tank; the first sleeve is fixedly sleeved to the bottom inner wall of the water-collecting tray, and a second sleeve is fixedly connected to the top of the water storage tank, and the second sleeve is connected to the first sleeve. A first sleeve is fixedly connected to the second sleeve. A draining tray is fixedly sleeved on the inner wall of the second sleeve. A water outlet cylinder is fixedly sleeved on the inner wall of the draining tray. A transmission cylinder is movably sleeved on the inner wall of the water outlet cylinder through a first limiting ring. A transmission fan blade is fixedly sleeved on the inner wall of the transmission cylinder. A first pipe is movably sleeved on the inner wall of the transmission cylinder through a second limiting ring. By setting the transmission fan blade, when water flows, the water energy is converted into kinetic energy, causing the transmission cylinder to rotate. During this process, the roller moves on the wave-shaped annular curved surface, which can make the spray pipe reciprocate. This can achieve spraying of permeable layer materials at near and far distances. Furthermore, when the spray pipe moves, the adjustment pipe can prevent the pipe surface from being damaged during the movement, which is beneficial to improving the protective effect on the permeable layer material.

[0006] Preferably, the surface of the drain tray is a wavy curved surface, and the top of the transmission cylinder is provided with a wavy annular curved surface.

[0007] Preferably, the permeable layer is composed of a crushed stone subbase, a permeable concrete base layer, a permeable concrete surface layer, and a surface pavement layer in sequence.

[0008] Preferably, a number of guide vanes are fixedly connected to the inner walls on both sides of the frame. By setting the guide vanes, the present invention can prevent rainwater from flowing outward from the perimeter of the frame during the rainy season, thereby realizing the function of concentrated drainage of rainwater into the ground, which is beneficial to improving the performance of the device.

[0009] Preferably, the spraying unit includes a water collection box, which is fixedly connected to the top of the first pipe. A plurality of spray pipes are fixedly connected to the top of the water collection box, and the spray pipes are arranged in a circular array. Rollers are movably fitted onto the outer wall of each spray pipe, and the rollers contact a corrugated surface. A fixed frame is fixedly connected to the inner wall of the top of the water storage tank. A water outlet pipe is fixedly connected to the bottom of the water outlet cylinder, and the water outlet pipe is fixedly fitted onto the inner wall of the fixed frame. A high-pressure water pump is fixedly connected to the inner wall of the bottom of the water storage tank, and the water outlet pipe is fixedly connected to the output end of the high-pressure water pump. In the high temperatures of summer, the invention uses the high-pressure water pump to spray water from the water outlet pipe onto the permeable layer, preventing the material in the permeable layer from hardening and affecting its permeability. Simultaneously, during the water flow, the transmission fan blades can convert water energy into kinetic energy, providing power support to the protective mechanism, which helps improve the reliability of the device.

[0010] Preferably, one end of the spray pipe is fixedly connected to an adjusting pipe, and a flow groove is provided on the top of the fixing frame.

[0011] Preferably, the water storage unit includes a water-blocking plate, which is fixedly connected to the inner wall of the bottom of the water storage tank.

[0012] Preferably, a through hole is provided on one side of the inner wall of the water-blocking plate, and a second pipe is fixedly connected to one side of the water storage tank.

[0013] A construction method for a sponge-type road pavement structure includes the following steps:

[0014] S1. Design and construction plan and prefabricated paving frame: Design the road according to geological conditions and rainfall, and manufacture the paving frame using external shaping equipment;

[0015] S2, Road geological treatment;

[0016] S2.1 Ground treatment and installation: The road surface is broken, leveled and compacted to ensure that the ground flatness meets the requirements, and a water storage tank is installed, and the second pipe is connected to the external drainage system;

[0017] S2.2, Sub-base treatment: Apply mortar to the ground to ensure a smoother sub-base for the permeable pavement, facilitating subsequent road paving;

[0018] S2.3, Paving a sponge-type road: The paving frame is connected sequentially by hooks on the paving frame on the road surface, and the gravel cushion layer, permeable concrete base layer, permeable concrete surface layer and surface pavement layer in the permeable layer are laid in sequence. During this process, the paving is observed to see if it is neat and flat through external testing equipment. Water permeable holes are opened in the pavement layer so that rainwater can smoothly enter the permeable layer and drain into the ground. At the same time, a filter layer is set in the water outlet to prevent the water outlet from being blocked.

[0019] S3, for use during the rainy season;

[0020] S3.1 Use in rainy weather: Rainwater flows from the permeable layer into the water collection tray from the laying frame, and then from the first sleeve through the second sleeve into the water storage tank. When the rainwater flows through the drain tray, it flows downward through the holes and corrugated surface on the drain tray. Some of the water flowing downward will pass through the fixed frame and flow into the water storage tank through the flow channel. When there is too much rainwater in the water storage tank, it flows into the drainage system through the through hole and the second pipe. During this process, the water will not flow from the outlet tube into the outlet pipe.

[0021] S3.2 In hot summer weather, when the water level in the reservoir is too low, a second pipe is connected to an external water pump to allow external water to flow into the reservoir. The water then flows out from the output of the high-pressure water pump and into the outlet cylinder through the outlet pipe. As the water passes through the drive fan blades, the water energy is converted into kinetic energy, which drives the drive cylinder to rotate. During this process, the drive fan blades rotate, and the spray pipe reciprocates through the wave-shaped annular surface, adjusting the water flow direction and height to spray the permeable layer. This prevents damage to the permeable layer due to long-term drought and ensures that the permeable layer can absorb water normally.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This invention, by setting up a transmission fan blade, converts water energy into kinetic energy to rotate the transmission cylinder when water flows. During this process, the roller moves on the wave-shaped annular curved surface, which makes the spray pipe reciprocate. This can achieve spraying of permeable layer materials at both near and far distances. Furthermore, when the spray pipe is moving, the adjustment pipe can prevent damage to the pipe surface during movement, which helps to improve the protective effect on the permeable layer material.

[0024] 2. By setting up guide vanes, this invention can prevent rainwater from flowing outward from the frame during the rainy season, thus enabling rainwater to be concentrated and discharged into the ground, which is beneficial to improving the effectiveness of the device.

[0025] 3. In the high temperatures of summer, the present invention uses a high-pressure water pump to spray water from the outlet pipe onto the permeable layer, preventing the material in the permeable layer from hardening and affecting its permeability. At the same time, during the flow of water, the transmission fan blades can convert the water energy into rotatable energy to provide power support for the protective mechanism, which helps to improve the reliability of the device.

[0033] like Figures 1 to 6As shown, the present invention relates to a sponge-type road pavement structure, including a paving frame 1 with several slots. It is worth noting that by setting the bottom of the paving frame 1 into an arch shape, the load-bearing capacity of the device can be improved during use. In contrast, existing sponge-type road pavement paving frames 1 are mostly rectangular, with limited load-bearing capacity. A fixing nail 101 is fixedly connected to the bottom of the paving frame 1, and a water-collecting tray 102 is provided at the bottom of the paving frame 1, with the fixing nail 101 fixedly sleeved in the hole on the water-collecting tray 102. A support frame 2 is fixedly connected to the inner wall of the frame 1. A frame 3 is fixedly connected to the top of the support frame 2. A permeable layer 4 is fixedly connected inside the frame 3. A water storage tank 5 is set at the bottom of the frame 1. A protective mechanism 6 is set between the water holding tray 102 and the water storage tank 5. The protective mechanism 6 includes a sleeve 601 and a spraying unit 7. A water storage unit 8 is set inside the water storage tank 5. The first sleeve 601 is fixedly sleeved on the bottom inner wall of the water holding tray 102. A second sleeve 602 is fixedly connected to the top of the water storage tank 5, and the second sleeve 602 is connected to the first sleeve. 601 is fixedly connected. A drain tray 603 is fixedly sleeved on the inner wall of the second sleeve 602. A water outlet cylinder 604 is fixedly sleeved on the inner wall of the drain tray 603. A transmission cylinder 605 is movably sleeved on the inner wall of the water outlet cylinder 604 through a first limiting ring. A transmission fan blade 606 is fixedly sleeved on the inner wall of the transmission cylinder 605. A first pipe 607 is movably sleeved on the inner wall of the transmission cylinder 605 through a second limiting ring. The surface of the drain tray 603 is a wavy curved surface 603a. The top of the transmission cylinder 605 is provided with a wavy annular curved surface 605a. This invention, by setting up a transmission fan blade 606, converts water energy into kinetic energy to rotate the transmission cylinder 605 when water flows. During this process, the roller 703 moves on the wave-shaped annular curved surface 605a, which causes the spray pipe 702 to reciprocate. This enables spraying of the permeable layer 4 material at both near and far distances. Furthermore, when the spray pipe 702 moves, the adjusting pipe 702a can prevent damage to the pipe surface during movement, which helps to improve the protective effect on the permeable layer 4 material.

[0034] In an embodiment of the present invention, the permeable layer 4 is composed of a crushed stone cushion layer, a permeable concrete base layer, a permeable concrete surface layer, and a surface pavement layer in sequence. Several guide plates 301 are fixedly connected to the inner walls on both sides of the frame 3. By setting the guide plates 301, the present invention can prevent rainwater from flowing outward from all sides of the frame 3 during the rainy season, thereby realizing the function of concentrated drainage of rainwater into the ground, which is beneficial to improving the use effect of the device.

[0035] In an embodiment of the present invention, the spraying unit 7 includes a water collection box 701, which is fixedly connected to the top of the first pipe 607. A plurality of spray pipes 702 are fixedly connected to the top of the water collection box 701 and are arranged in a circular array. Rollers 703 are movably sleeved on the outer wall of each spray pipe 702 and contact the surface of the corrugated surface 603a. A fixing frame 704 is fixedly connected to the inner wall of the top of the water storage tank 5. A water outlet pipe 705 is fixedly connected to the bottom of the water outlet cylinder 604 and is fixedly sleeved on the inner wall of the fixing frame 704. A high-pressure water outlet pipe 705 is fixedly connected to the inner wall of the bottom of the water storage tank 5. The high-pressure water pump 706 and the outlet pipe 705 are fixedly connected to the output end of the high-pressure water pump 706. One end of the spray pipe 702 is fixedly connected to the regulating pipe 702a. The top of the fixed frame 704 is provided with a flow groove 704a. In the high temperature of summer, the high-pressure water pump 706 works to make water flow out from the outlet pipe 705 to spray the permeable layer 4, preventing the material in the permeable layer 4 from hardening and affecting the water permeability of the permeable layer 4. At the same time, during the flow of water, the water energy can be converted into rotational energy through the transmission fan blade 606 to provide power support for the protective mechanism 6, which is beneficial to improving the reliability of the device.

[0036] In another embodiment of the present invention, the water storage unit 8 includes a water-blocking plate 801, which is fixedly connected to the inner wall of the bottom of the water storage tank 5. A through hole 802 is opened on one side of the inner wall of the water-blocking plate 801, and a second pipe 803 is fixedly connected to one side of the water storage tank 5. In the case of high temperature, when the water level in the water storage tank 5 drops, the present invention connects to an external water pump through the second pipe 803 to replenish water in the water storage tank 5 and spray the permeable layer 4 material, which is beneficial to improving the use effect of the device.

[0037] As another embodiment of the present invention, a construction method for a sponge-type road pavement structure includes the following steps:

[0038] S1. Design and construction plan and prefabricated paving frame 1: Design the road according to geological conditions and rainfall, and manufacture the paving frame 1 using external shaping equipment;

[0039] S2, Road geological treatment;

[0040] S2.1 Ground treatment and installation: The road surface is broken, leveled and compacted to ensure that the flatness of the ground meets the requirements, and a water storage tank 5 is installed, and the second pipe 803 is connected to the external drainage system.

[0041] S2.2, Sub-base treatment: Apply mortar to the ground to ensure a smoother sub-base for the permeable pavement, facilitating subsequent road paving;

[0042] S2.3, Paving a sponge-type road: The paving frame 1 is connected sequentially by hooks on the paving frame 1 on the road surface, and the crushed stone cushion layer, permeable concrete base layer, permeable concrete surface layer and surface pavement layer in the permeable layer 4 are laid in sequence. During this process, the paving is observed to be neat and flat by external testing equipment. Water permeable holes are opened in the pavement layer so that rainwater can smoothly enter the permeable layer 4 and drain into the ground. At the same time, a filter layer is set in the water outlet to prevent the water outlet from being blocked.

[0043] S3, for use during the rainy season;

[0044] S3.1 Use in rainy weather: Rainwater flows from the laying frame 1 into the water-collecting tray 102 through the permeable layer 4, and then from the first sleeve 601 through the second sleeve 602 into the water storage tank 5. When the rainwater flows through the drain tray 603, it flows downward through the holes and the corrugated surface 603a on the drain tray 603. When some of the water flows downward, it will pass through the fixed frame 704 and flow into the water storage tank 5 through the flow channel 704a. When there is too much rainwater in the water storage tank 5, it flows into the drainage system through the through hole 802 and the second pipe 803. During this process, the water will not flow from the outlet pipe 604 into the outlet pipe 705.

[0045] S3.2 In hot summer weather, when the water level in the reservoir 5 is too low, the external water pump is connected through the second pipe 803 to allow external water to flow into the reservoir 5. After the high-pressure water pump 706 operates, the water flows out from the output end of the high-pressure water pump 706 and flows into the outlet cylinder 604 through the outlet pipe 705. When the water passes through the drive fan blade 606, the water energy can be converted into kinetic energy. The drive fan blade 606 drives the drive cylinder 605 to rotate. During this process, the drive fan blade 606 rotates, and the spray pipe 702 reciprocates through the wave-shaped annular curved surface 605a to adjust the water flow direction and height, spraying the permeable layer 4 to prevent damage to the permeable layer 4 due to long-term drought and affect the normal water absorption capacity of the permeable layer 4.

Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
